Dear sir/madam, I have been asked at my school to do an experiment in order to determine the solubility of calcium carbonate. The steps are as follows. 1. dissolve 5g Calcium chloride in 100ml distilled water, and do the same for sodium carbonate. 2. Mix the solutions thoroughly and retain all of the precipitate. 3. Weigh a piece of filter paper and seperate the precipitate from the solution. 4. leave the solid to dry overnight. In my exp. I got 1.2 g less calcium carbonate than i expected from my calculations. The amount I expected was 4.554 g, but i got only 3.328 g. I am 100% sure that the expirement was acuurate and I lost no material!
